To all whom it may concern.'

Be .it known that l, SAMUEL Manner., a

citizen of the United States, residing at Pipestone, in the county ofPipestone and State ol: Minnesota, have invented a new and useful Mold for Constructing Hollow Reinforced-Concrete lValls, of which the following is a specification. 1

T he invention relates to improvements in molds for making hollow reinforced concrete walls. f

The object of the present invention. is tol invention consists in the constructionv and novel combination of parts hereinafter fully described,illustrated in .the accompanying drawings, and pointed out in the claims hereto appended; it being .understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to with'- out departing from the'spirit or sacrificing any of the advantages of the `invention.

ln the drawings :f-Figure 1 is aperspective view ofia mold, constructed in accord.

ance with this invention and shown applied to a wall. Fig. 2 is a plan vieu/ofthe same partly in section. .Figa 3 is a vertical sec.4 tional view of. the same,v the parts being arranged for making the upper course. Fig. 4 is a similar view, the parts beingarranged l for constructing the lower course.

position byV the saine and constituting" side walls of themold. Theside .planking is preferably two feet in'width andjis ad?.

justable frorn'the lower to the upper portion. 1

of the frame-work of the mold ttor enabling two courses of approximately two feet to be successively moldedv or constructed before changingr the position of the moldl'onjthe wall. The p'osts or standards are connected ateach side of the mold to form the trame work thereof by meansof inclined longitudinally disposed braces 5, preferably'.conn sisting of rods provided at their ends with eyes or openings 6, and secured to the standw ards or posts by upper and lower transverse connecting. rods 7 and 8, which pierce the standards orposts and hold the same againsty y outward movement and maintain the said standards or posts in proper contact with'the transverse gage bars, whereby the-proper thickness of the wall-is maintained andthe frame work secured in plumb position;- Although the-braces are shown -in-theform of the inclined rods 5,. the braces, maybe constructed of .'wood, or other suitableina; terial and may be arranged in any other pre*` fer-red mannerto Secure the. 'requisite strength of the frame-work oi-themold.-

The frame-work may also be braced at fthe' corners or angles' by means of straight-hert zontal rods 9, which connect they adjacent `standards orf posts at the outer side of the mold. The transverse rods 7 and 8 have threaded terminals and are prmfidedv with nuts 10, `which engage either the standards or posts at the terminalsoit the braces.

The standards or posts are provided at their upper ends with. transversely alined l recesses 11, and the upper gage-barsare provided/at their endswith lowery recesses 12, forming terminalprojections lto-fiteill the recesses 1l of the upper Vends of .the standards or posts and `providing shoulders '14, whichengagethe standards or posts at the inner faces thereof tefjlimit the inward movement of the same, whereby the standards or posts are properly spaced at the top. The upper gage bars are also provided at their'lower edges with central. longitudinally alined lmacesses 15 for the reception ofv av longitudinal 'connecting bar 16A of cores 17, :when/the Vapparatus is arrarrgedl for moldingthe upper course, as illustratedin Fig'. 3 of'theaccompanying drawings.

The standards or posts are equippedkfat a 'point intermediate of their ends. withiapconnects the lpierce the cores and proxiir-iatelyl L-shaped brackets 18, designed to'be constructed of metal or other suitable material consistingv of a lower or base p ortion, and an upwardly projecting portion spaced from the standards or posts and forming a recess 19 to receive the lower transverse gage bar 3. The supporting brackets 18 are arranged in transverse alinement at the `side faces of the posts or stand ards, and' the lower transverse gage bars are provided with terminal recesses 20, located at the. lower edges of the gage bars and forming spaced projections 21 and 1nner shoulders 2:2. The upper projections lit in the recesses 19 of the supporting brackets, and the shoulders Q2 abut' against the inner side edges or faces of the brackets and limit the inward movement of the standards or posts and maintain the latter in proper spaced relation to provide a walletl the proper thickness and to form annular spaces for the bars are also provided in their upper edges i with central longitudinally alined recesses Q3 for the reception of the longitudinal connecting bar 16 of the cores 17. In molding the lower-.one of the two courses to be made by the mold, the longitudinal bar 1G, which cores, is arranged in the cetrally alined recesses 23 and is supported by the gage bars 3. The cores 17, which depend from the longitudinal connecting bar 16, are alternatel' secured at their upp ends to the opposite side faces of the same by means of transverse bolts 24: which the connecting bai' 1G. lhe cores are arranged in spaced overlapping relation, and are adapted to form two longitudinal series of vertical air spaces 25 in the wall 26, the vertical air spaces extending frointhe top to the bottom of the wall, and the airspaces of one series being arranged opposite the intervals between the air spaces of the other series, and extending Abeyond the planes of the end walls of such air' spaces, as' clearly shown in Fig. 2 of the drawings. By this arrangement the entire length' of the wall is interrupted by air spaces and is thereby rendered frost-proof. ie cores have al slight downward taper' from their upper to `their lower ends to enable them to be readily introduced into the air spaces of the wall previously made, and to permit thcin to be easily Withdrawn from the conffzrete al'ter the saine has set.'

nstai'ting the work upon the foundation, the mold is set up on the v'foundation and is made plumb by fastening the structure together, a corner being always used. The top ot the foundation must be, level, or the framelworl:.must be leveled up. The standards or posts after-being set u surface are made plumb' by the use oic the upper and lower transverse gage ha rs, which arfxurutrly spul-o tho standards or posts at are then placed in position and p on a level' the top and center theexact distance required to mold the wall :in d to provide the necessary space for the side planking or side walls of the mold, and the said standards or posts are firmly held in such position by tightening the upper and lower horizontal transverse rods. The planlcing is then placed on the inside of the framework againsttlic inner `faces of the standards or posts and the mold is then ready to begin work. After the first course has been molded, the apparatus is mounted upon the same in the following manner: 'The standards or posts are placed over the wall and are let down until the lower horizontal transverse rods 8 rest upon the top of the wall. The lower ends of the standards or posts are spaced from the sides of the wall the proper distance by means oi blocks 27, which are dctaclialily secured by screws 28, or other suitable fastening devices to the inner laccs o the standards or posts below the lower transverse rods 8, as clearly illustrated in Figsi 3 and 4 of the drawings. The lower ends of the standards or posts may be beveled, as shown, or cut square. e upper and lo`fer transverse gage bars the transverse rods tightened to hold the fra ie-work firmly in position. The side planlring or walls are then placed in position and the work is continued. ln molding bari's placed in the upper recesses 23 of the lower gage bars 3 and are supported rby the latter, as .-lcarlv illustrated in Fig. 4 ot' the drawings. After the first course has been set, the side planking or walls are raised to the upper portion of the framework for molding the second course, being Y the wall, or a secliing or wall sections may be placed upon the side planking previously 'The cores are then elevated, the longitudinal core connecting bar being supported upon the upper transverse rods 7 and being held in proper position cen-- ti-ally-ot the wall by the lower central recesses 15 of the` upper gage clearly-illustrated in Fig. 3 of the drawings.

'lhe concrete wall may be reinforced'b'y vertical rods 29, horizontal connecting wires El() and transverse reinforcing members 3l. The rods 25) are arranged in a vertical position at suitable intervals, and the connecting wires 39 are arranged horizontally at regular'intcryals and are suitably connected to vthe rods. The transverse eiiiforcin nioi'nbers Ill are arranged horizontall and have angulaily bent terminals extendin in opposite directions. These transverse reinforcing members may be arranged either in straight transverse lines at right angles bars 2, as.

1,123,57os @i to the planes of the side faces of the Walls,

as illustrated in Fig. 1 of the drawings, or-

they may be disposed diagonally, as shown in Fig. .any other reinforcing material may, however, be en'ibedded Iin the concrete.

When desired, the wall may be Waterproof' by putting on the outside a coating of about a quarter of an inch in tliiclfzness of cement mixed with sand in the proportion ot two of sand to one 0.3" cement. The coating may be left smootlnor may be made to represent brick or stone and colorinff matter may' be used to gire the desired e ect.

ilario thus fully described my invention, what I ciiin as new4 and desire to secure by Letters Patent, is rl. A mold of the class described comprising a 'iraineworlr including spaced standards arranged, in pairs, transverse rods oonnecting the standards and having. adjusting means for moving the standards inwardly, and gage bars extending across the mold and engaging and spacing the standards at a point above the said rods, a bar extending longitudinally of the mold between the standards thereof and engaged by the gage bars and supported by the said transverse rods, and a series of cores connected with and supported by the said bar.

EZ. A mold of the class described comprising a framework including spaced stendards arranged in pairs, lower tiecsverse rods connecting the lstandards and having adjusting means for moving the standard inwardly to clamp them against a wall, gage bars'extcnding across the mold and engaging and spacing the upper endsy of the standards and upper transverse rods located beneath the gage bars and connecting the standards, a bar extending longitudinally of the'inold between the standards thereof and engaged by the-gage bars and supported by the upper transverse bars, and a series of;

cores connected with and supported by the said bar.

3. A mold of the class described including standards arrangedin pairs, transversely alined brackets carried by the standards and located at points intermediate of their ends, gage bars having terminal recesses to'it the brackets5 means for adjustably connecting the standards to clamp the same against a wall, and a core having a longitudinal bar supported by-the said gage bars.

l. A mold ot' the class described comprising a iran'iework including standards arranged in pairs and provided at their upper ends with transversely alined recesses, transversely alincd brackets carried by the standards and located at points intermediate of their ends, gage bars having terminal recesses to fit the brackets and the upper recesses of the standards and means located below the gage bars for adjustably connecting the standards to clamp the. saine against a wall, whereby the framework is adjustably, mounted thereon, side walls arranged at the inner faces of the standards, and a core having a longitudinal supporting bar adapted to engage with the said gage bars and. siiiflable from the lower to the upper portion of themold.
